"South By South West, what's happenin'?" T.I. yelled out from stage at his first SXSW, as he greeted the eager audience at Thursday night's Warner Music Group showcase in Austin, Texas. Massive lines formed around the block of downtown venue La Zona Rosa hours prior to the hip-hop-themed final installment of "The Warner Sound Captured By Nikon," a two-day and three-night event whose evening shows were live-streamed via WMG's newly launched YouTube Channel, "The Warner Sound."

Up top, check out a brief clip of Tip's performance of "I'm Back." You can also check below for footage of him and B.o.B performing "On Top Of The World" & "I'm Dat N*gga." Before launching into "I'm That N*gga," Tip made mention that it was the first song that B.o.B and himself ever recorded, and since they rarely perform together, asked that the crowd consider themselves "privileged and lucky."
